Group the data by program units

Use the Timeline grouping menu to select a grouping level:

A grouping level depends on the analysis type. Selected grouping affects the metrics provided in the Timeline pane. If some of the metrics are not supported for the selected grouping, this data does not show up in the Timeline view and the legend is updated accordingly.

Sort the data

Right-click the list of threads/cores/CPUs (depending on the analysis type) and select the required type of sorting from the Sort By content menu option:

  • Row Start Time sorts the rows by the thread creation time.

  • Row Label sorts the rows alphabetically.

  • <Metric> sorts the rows by performance metric monitored for the selected viewpoint, for example, CPU Time, Hardware Event Count, and others.

  • Ascending sorts the program units in the ascending order by one of the categories selected above.

  • Descending sorts the program units in the descending order by one of the categories selected above.

Re-order the rows

Select the row you need, hold and drag it to the required position. Press SHIFT to select multiple adjacent rows. Press CTRL to select multiple disjointed rows.

Filter data

Select the required program unit(s), right-click and choose from the context menu to filter in or filter out the data in the view by the selected items. To go back to the default view, select the Remove All Filters option.
